Changing of Material Valuation Classes

Question

Currently changing of material valuation classes in standard SAP can be achieved if :
    1.   If valuated stocks already exist, you can change the valuation class
        only as follows:
        a)  Post the stocks of the material to an interim account.
        b)  Change the valuation class in the material master record.
        c)  Post the stocks of the material back to their original account
    2.   If open purchase orders already exist, you can only change the
        valuation class if you first flag the corresponding purchase order
        items for deletion.
    3.   If production orders exist for which a goods movement has already
        taken place, you can only change the valuation class if you first
        set the status of the production orders to Deleted.
Is there any other ways that point 2 and 3 can be avoided when trying to change material valuation classes?
Thanks,
CW

Answer 1

HI,
That makes it very tricky doesn't it.
But if this is done at your quietes time (if there is one, but even 24hour 7 day operations have a quiet time?)
You can still carry on producing but yopu will have to hold off from posting anything while the PP orders are blocked/deleted.
I guess that you could use an LSMW job to make sure that the time taken is a minimum.
The job just needs to be fed a list of all PP orders containing the material/s involved and it can then set the delete flags and reset them in  seconds (with a manual change of the Valuation class inbetween).
There is not going to be a clean and easy solution to this, all we can do is to try to reduce the pain.
